Lumen OHM Assessment

Given the function below, determine if the function is continuous at the point `x=1`. If not, indicate why.

`f(x) = (1-x^2)/(1-x)`

Continuous at `x = 1`
Not continuous: `f(1)` is not defined; this is a removable discontinuity
Not continuous: `f(1)` is not defined; this is not a removable discontinuity
Not continuous: `lim_(x rarr 1) f(x)` does not exist
Not continuous: `f(1)` and limit exist, but are not equal
